Microsoft's new toolbar, much better than the MSN toolbar, this one is supposed to have phishing filter technology inbuilt and it allows for tabbed browsing even if you are using IE 6

Have been using this for 4-5 days now, and its pretty useful, has not crashed..YET... and seems to pretty much keep out of my way most of the times....

BTW has anyone used Live search yet? I did not like the interface at all, it takes so long just to load the pasge.
